'Witnessed' in the Bible

And Peter solemnly testified and continued to admonish and urge them with many more words, saying, “Be saved from this crooked and unjust generation!”

Then when he arrived and witnessed the grace of God, he rejoiced and began to encourage them all with resolute heart to remain true to the Lord;

But on the night immediately following, the Lord stood at his side and said, “Take courage; for as you have solemnly witnessed to My cause at Jerusalem, so you must witness at Rome also.”

After arranging a day with him, many came to him at his lodging. From dawn to dusk he expounded and witnessed about the kingdom of God. He tried to persuade them concerning Jesus from both the Law of Moses and the Prophets.
